FLUID-HOLDING PENCIL.

SPECIFICATION forming part of Letters Patent No. 501,958, dated July 25,1893.

Application filed February 13, 1893. Serial No. 462,152. (No model.)

To all whom it may concern;

Be it known that we, WALTER B. OLMSTED, HERBERT O. WARNER, and HOWARD A.GID- DINGS, of Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in Fluid-Holding Pencils, of which the following is a full, clear, and exactdescription, whereby any one skilled in the art can make and use thesame.

This invention appertains to fluid holding pencils, and especiallyrelates to ink-erasers.

The object of this invention is to provide a fluid holding pencil orink-eraser which shall be simple and cheap in construction and may bequickly and easily filled.

With this object in view theinvention consists essentially in a fluidholding pencil, comprising a tubular portion to contain the fluid havinga conical or tapered lower end with a small puncture or outlet therein,a flanged upper end having a small inlet opening, and means forhermetically closing said inlet; and it also consists in the particularconstruction and in the combination and arrangement of the partssubstantially as hereinafter more particularly described and as setforth in the claims.

Referring to the drawings: Figure l represents in central longitudinalsection a fluid holding pencil constructed substantially in accordancewith this invention. Figs. 2, 3 and 4 are sectional details showingmodified forms of tops and closures. Fig. 5 isa detail of the stoppershowing cement coating.

In the drawings the letter a represents the fluid holding pencil whichwill preferably be formed of glass having the tubular body I) to containthe fluid tapered at its lower end as at c with a longitudinal punctured therein. The upper end a of the tubeb will preferably have an internalflange'fremote from the upper end with an inlet openingg therethrough asshown in Fig. 1, in which figure the pencil is shown as straight fromthe extreme upper end to the .base of the conical pointed end 0. Thisparticularconstruction is preferable but it will be obvious that theupper end of the pencil might be formed as illustrated in Figs. 2, 3 andA.

The pencil is charged with fluid through the inlet 9 in the upper end 6,which end is hermetically sealed, preferably by a stopple h subjected toa coating of hot glue or cement 2' see Fig. 5, which stopple is insertedinto the neck of the pencil while the glue or cement is in a molten orheated condition the setting of the glue or cement insuring an air tightjoint. After filling the pencil and inserting the stopple the mouth ofthe pencil above the stopple may be filled with cement or wax, as shownat 2', Figs. 1, 2 and 3.

The filling and sealing of the pencil together with simplicity andcheapness in cost of manufacture are the chief objects of this presentinvention, and its advantages will be readily apparent to any oneskilled in the art to which it appertains. By this construction andarrangement the pencil may be inverted in the pocket Without liabilityof leakage. It is obvious that the subsequent filling of mouth of thepencil above the stopple, after the same is in place might be dispensedwith without departing from the spirit of our invention.

I We claim as our invention- 1. As an improved article of manufacture, atubular fluid containing pencil having a punctured and tapered lowerend, and an internally flanged upper end with an inlet openingtherethrough, in combination with a stopple to hermetically seal saidinlet, substantially as described.

2. An ink-eraserpencil consisting of a tubular body containing a fluid,and having a tapered punctured marking end and an internally flangedupper end with an inlet opening therethrough, a stopple inserted in theupper end of said pencil with glue or cement interposed between thestopple and neck of the pencil to hermetically seal the same,substantially as described. 7

3. The pencil having the tubular body I) filled with fluid, and havingthe tapered end 0 with the puncture dtherethrough, the flange fnear theupper end of the tube having the inlet opening 9 therethrough, incombination with the stopple h having the cement or glue 1', and thesupplemental coating 2" to cover the face of the stopple, substantiallyas and for the purpose described.

4. As an improved article of manufacture a tubular fluid containingpencil having a cased in a coating of hardened adhesive ma- IO puncturedand tapered lower end and with an terial, all substantially asdescribed.
